ath12k firmware regression with update 82318c966fd1
Hi,
it seems that the recent update of ath12k WCN7850 board-2.bin update broke WiFi on Lenovo Thinkpad 14 Gen 5 AMD. Reverting to the older firmware seems fixing the issue.
The report for openSUSE Tumbleweed is found at
https://bugzilla.suse.com/show_bug.cgi?id=1230596
and for Arch
https://bbs.archlinux.org/viewtopic.php?id=299286
Let me know if it's already handled in Qualcomm and the fix is expected shortly. Otherwise I'll try to revert the change locally for TW as a temporary solution.
thanks,
Takashi

Just to clarify, reverting to an older board-2.bin seems to fix the issue. (Board files are basically calibration data)

This is the first time I'm hearing about this and to my knowledge there is not fix pending.
